MECHANICALLY ACTUATED TOOL.

Application filed January 12, 1912. Serial No. 670,761).

To all whom it may concern:

Be it known that L-EDWARD H. THOMP- sonx a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Mechanically-Actuated Tools, of which the following is a specification.

This invention relates to mechanically ac-' tuated tools and particularly to brushes and similar deviceswhich are ada' ted to utilize water or other liquids or flui ing theirfunctions. I

An object of this invention is to produce a new and improved device of'the 'kind s in performabove described, which can be. more 0011- veniently employed and is more effective in operation, than similar apparatus now in use or known to me. These and other objects I attain by means of a device embodying the featuresherein described, and illustrated inthe drawings accompanying and formingfa part 013 this application.

I In the drawings Figure 1 is a longitudi-j nal sectional View along the line 1+-1 of Fig. 2 and illustrates a mechanically actuated brush as an embodiment of my invention. Fig. 2 is a transverse sectional view alongthe line 2 of Fi 1, looking in the direction of the a row. ig, Sis a sectional ,viewyalong the line'33 of Fig. 1 looking in the direction of thearrow.

The illustrated embodiment of my inven-- tion consists of a water turbine t'and brush 5 which is mounted on, or is directly connected to the shaft 6 of the turbine and is ada ted to receive the water discharged from t e turbine after it has been employed in imparting motionto the rotor element of the turbine. The turbine illustrated includes a casing-7, which incloses rotor e1e' ment 8, and is providedfwith a liquid supply passage 9, preferably, but not necessarily, formed integrally with the casin and adapted to be employed as a handle or the device. An admission ort oranozzle 10 extends .throu h the cyllndrical wall of the casing 7 an delivers liquid from the pee sage 9 to the rotor element 8, which is here: in illustrated as a hollow drum provided around its periphery with integrally formed blades 11.. The ,drum'. is rigidly mounted on the shaft 6, oneend of which is jour- I naled in a suitablestep or thrust bearing formed in one end of the casing 7. The ot ller'end of the shaft projects through, and

is journaled in, an aperture )rovided in a removable plate 12..which orms the exhaust end of the turbine casing" and is provided with a suitably located'exhaust port 13. The plate 12, is made removable so that the rotor element 8 can-.be introduced into the turbine and it is adapted to engage an annular shoulder, formed on the casing proper, and to be secured in place by any suitable nieans, such for example as'screws. A longitudinally projecting annular flange 14 is formed on the exhaust-end of the caswhich is concentric with the ture shaft will tend to screw the brush into place on it. Itwill be understood, however,

that any suitable means may be employed for mounting the brush on, or directly connecting it to the shaft 6; Thebrush may be of any suitable typebut it is preferably provided with'a circular body, on one side of which the bristles 16-are mounted in any suitable manner and on the other side of which a cylindrical extension 17 is formed.

The nut 15 is so located in the extension that the extension is concentric with the sha'ftfi and is adapted to project into thecylindric'al space surrounded by the flange 14. An, an-

nular series of apertures 18 is formed in the body of the brush for the purpose of deliver ing the water discharged from the exhaust 'port 13 to the bristles G or to, the operating face of the brush. The'seapertures"extend from the circular face of the extension to '"the bristle-mounting face ofthe brush and are adapted to successively receive the water discharged from the port 13, as the brush rotates with the shaft. 6. A seriesof directing vanes is mounted on the circular fach of the extension and is located between it and the plate 12. Each vane of the series is adapted to direct the flow of water discharged from the port 13 into one of the apertures 18 and also operates to impede the motion, or to decrease the speed of rotation of the brush. This latterfunction ofthe vane is, not objectionable since, with the type of turbine illustrated, the brush speeds produced by an amount of water, which can be edectively employed in the scrubbing operation of the brush, would be prohibitive, if the water were delivered to the turbine at ordinary watermain pressures. For

this reason it may sometimes be desirable to so form the vanes that their impeding efiect on the brush will be quite marked Each vane 20 illustrated extends from a point, on the body or the brush immediately adjacent to the shaft (3, in a substantially radial direction alongone edge of one of the apertures 18 to the outer end of the aperture at which point it is curved to conform to the contour of a portion of the edge to the aperture and then projects approximately at a right angle to a radial direction and extends to the peripheral edge of the extension 17 and into close proximity with the inner cylindrical ace of the an nular flange 14:. The outer ends ot the vanes extend in a direction opposite to the direction of rotation of the brush and each vane operates to collect a portion of the water discharged from the port 13 and to direct it through its corresponding aperture 18. The tendency of the water discharged from the port 13 is to move outwardly in response to the centrifugal force resulting from the rotary motion imparted to it by the brush. This tendency is, however, overcome by the blades and if desired the blades may be so formed that they will direct the water inwardly toward the shaft 6. The form of the vanes 20 may be varied considerably without departing from 'my invention.

In the apparatus illustrated T have pro vided, what may be termed, wearing strips 21 between. the cylindrical face of the extension 17 and the inner peripheral face of the flange 14:. These strips may be formed of soft metal rabbeted into, or otherwise so cured to the extension and may be of such altitude that they will engage the inner face of the flange when the brush is first mounted on the shaft. With this arrangement the rotation of the. shaft will wear the strips down until they just clear the inner face of the flange so that they will be capable of preventing a flow of Water between the flange and the extension without materially impeding the rotation of the brush. Various other formsof packing, however, may be employed between the extension and the flange if it is found necessary to use a packing.

The passage 9 is preferably several feetlong, sothat it can he efl'ectively employed as a handle for the derice, and it is prorided at its outer end with suitable means for connecting it to a hose or any other source of supply.

lt will be understood that although I have illustrated a water turbine in connection with my invention that I am not restricted to the type of turbine illustrated, or even to turbine engines since any type of rotary engine may be employed. In addition to this I do not limit myself to water as a motive fluid since air, steam or liquids other than water may be employed. I also wish it to be understood that tools other than brushes may be employed 'in connection with my lnrention. For example my invention may be embodied in a floor surfacing machine in which the water discharged from' strong to effectively resist the forces en-- countered, they do not materially add to the weight of the device. What T claim is 1. In a device of the character described,

a turbine consisting of a rotor element, a

casing inclosing said element and having an inlet port and a laterally disposed exhaust port, a brush mounted on the shaft of the turbine adjacent to the exhaust port, and having transversely. extending apertures formed in its body pottionwhich successively pass the-exhaust port, and directing vanes mounted on the brush. between the brush and the casing, each vane extending radially along one edge of one of the apertures and then at rightangles at a point adjacent to the periphery of the brush.

2. A fluid actuated turbine, a tool mounted on the shaft of the turbine and located adjacent to the exhaust port thereof, and

port of the turbine for directing the flow inlet port, an exhaust port and a-ldngitu and located between it and, the exhaust port dinally projecting externally located annular flange, surrounding the exhaust port a rotatable element mountedem'r the shaft of 5 the turbine exterior of the-casing-and partially surrounded by the flange, and directing vanes mounted on the rotatable-element of the turbine.
